Title: Optical attenuator
Inventor: IWATSUKA SHINJI
IPC: G02F1/09
Filed: 1991-06-04
Abstract: PURPOSE:To simplify the structure and to easily vary the attenuation quantity by varying an external magnetic field by using a perpendicularly magnetized magnetooptic material in the variable impressed magnetic field. CONSTITUTION:This optical attenuator attenuates transmitted light by diffracting incident light by impressing the variable magnetic field from an electromagnet 2, etc., to a magnetooptic element 1 which has multiple magnetic domain structure in the absence of the impressed magnetic field and generate mutually different mgnetism components parallel to the incident light in adjacent magnetic domains. This optical attenuator functions as an optical modulator by using a means which can impress a modulating magnetic field. This magnetooptic element 1 preferably uses bismuth substituted rare earth iron garnet, etc. In general, diffraction loss is maximum when no magnetic field is pressed and decreases by the movement of a magnetic wall as the impressed magnetic field increases. The multiple magnetic domain structure of the element turns into single magnetic domain structure above a saturated magnetic field, so no diffraction is caused. In this case, the intensity of direct light is adjusted with the diffraction loss by the magnetooptic element 1, so a polarizer can be omitted, which is advantageous in structure.

Title: Driving condition detecting device
Inventor: KITA TOORU
IPC: G01M17/00
Filed: 1983-08-31
Abstract: PURPOSE:To ensure the detection of both larger and smaller changes in the vehicle attitude by detecting the load on nor movement of the suspension system by a load sensor disposed in the suspension system, and by detecting driving conditions based on said detected signal. CONSTITUTION:The signal DS from a load sensor 8 disposed in a suspension system attachment on the vehicle side is zero under a steady static load.

IPC: H02P7/29
Filed: 1979-12-06
Abstract: PURPOSE: To eliminate the infuluence of noises by dividing the reference frequency to 1/N by one control device, multiplying it N times by the other control device, and synchronizing with the reference signal.  
     CONSTITUTION: A pulse signal fCH 1  which is synchronized with the chopper frequency of the other phase obtained by a frequency divider 2 is transmitted and supplied to a phase comparator 6 together with a pulse signal fCH 2  which is synchronized with the chopper frequency of the own phase obtained by a frequency divider 3. Said phase comparator 6 sends out the AC output whose DC component becomes zero when the phase difference of the signal becomes the desired phase difference. Therefore, if fCH 2  is deviated from the desired phase difference, the AC wave having the DC component corresponding to the deviated phase difference is sent out. While the voltage VB is applied to a V/F converter 8 beforehand so that the frequency of the fCH 2  signal which is sent out via the frequency divider 3 becomes a specified frequency. Therefore, the DC component from a filter 7 and said VB are added or substracted, and the calculated voltage is applied to the V/F converter 8, wherein the oscillating frequency is varied depending on said voltage.

Filed: 1983-09-02
Abstract: PURPOSE:To obtain a molded piece free from cracking by using polyamide-imide resin with a specified soluble viscosity in compression molding of thermoplastic polyamide-imide resin. CONSTITUTION:Polyamide-imide resin is heat-treated. The heat-treatment changes the polyamide-imide resin having the maximum soluble viscosity 2X10<5> poises at 340 deg.C into the polyamide-imide resin having the minimum viscosity 3X10<5> poises under heating atmosphere. In this compression molding, the heated mold is filled with polyamide-imide resin powder that does not absorb water and has been heattreated and then, pressure is given to the powder as heated at the melting point min. After pressure is given, the mold is cooled and a molded piece is taken out of the mold. The molded piece obtained is postcured. Accordingly, though the mold is cooled after compression molding the molded piece is free from cracking. While the molded piece is taken out of the molded no cracking occurs. Additionally, in the post cure process cracking is prevented from occurrence.
